IRONING-MACHINE.

nooaetaf To all whom 'it maypconcem;

Be it known' that' L-AxnnR. GUSTAFSON, a citizen ofthe-'United"States,-,and residing at Chicago, thelcounty of Cook andState of IlllIlOlS, havefinvented ai new and useful Improvement inIroning Machines, of which the following a complete specification. l i 5a The main objects of this invention are to provide an improved ironing;machine for laundry purposes; to provide an improved ironing machinehaving improved mechanism for regulating the pressure of the ironironingmachine embodied in this invention.

Fig. 2 is an end elevation of the other end of the machine. Fig. 3 is afront elevation of the machine, with parts removed. Fig. 4 is anenlarged, fragmentary end elevation of the ironing rollers and the meansfor adjusting the same. Fig. 5 is an enlarged, fragmentary frontelevation of the ironing rollers and the means for adjusting the upperrollers with respect to the lower roller. Fig. 6 is a horizontal sectionof one of the channel guides and guide arms.

In the construction shown, a suitable frame is provided which comprisesend members 1 which are rigidly secured together by means of tieorfbrace rods 2. Rigidly secured on the tops of the end members law thebearing members 3 and 4 on which the operative mechanism is mounted. Thebearing members 3 and 4 are provided with bearings 5 and 6 in which isjournaled the heating roller 7, which is provided at its ends withtrunnions 8 and 9 mounted in said bearings. The heating roller 7 ishollow and is provided with ventilating apertures 10 in one end. Aburner 11, comprising a perforated pipe, rigidly secured in a bracket 12carrled on the member 3, and extends through the trunnion 8 into theSpecification of Letters Patent.

roller 7 The inner end of the burner is supported in a bearing 13 at theend of the roller, and the outer end of'the burner is connected with apipe 14 leading from a'gas supply, and provided with suitable cocks 15and 16 which are adapted to control the amount of gas entering theburner.

Extending upwardly and rearwardly from the bearings 5 and 6 are thechannel shaped guides 17, and slidably mounted in said guides is thecarriage 18 for the compression rollers 19 and 20. Said carriagecomprises end pieces 21, each of which is provided with a centrallydisposed, downwardly directed guide arm 22 which is slidably mountedinthe adjacent guide 17 and is provided with a slot 23 through which astop bolt 24 projects. Said bolts are rigidly secured in the guides 17and act to limit the movement of the carriage 18, and to prevent saidcarriage from being displaced from the bearing members 3 and 4:. EX-tending downwardly and laterally from each of the end pieces are arms 25in which tie rods 26 are secured to connect the end pieces together andcause them to move in unison. The compression rollers 19 and 20 arejournaled respectively in the rear and front sides of the carriage 18 inbearings 27 in the end pieces 21, and are each covered with canvas orother suitable material v28. 7

Extending outwardly from the upper end of each guide 17 is an aperturedlug 29', and extending upwardly on each end piece 21 is a bracket 30having an outwardly directed apertured lug 31. At each end of thecarriage is an adjusting shaft or bolt 32 which is rigidlysecured at itslower end in the lug 29, and at its upper end extends through and isloosely mounted in the lug 31. Carried on said shafts between the lugs29 and 31 are coiled springs 33 which normally act to hold the carriage18 in an elevated position with the compression rollers out of contactwith the heating roller. The upper end ofeach shaft 32 is screwthreaded,and having threaded engagement thereon is a hand wheel 34 which whenturned into engagement with the lug 31 acts to force the carriagedownwardly and increase the tension of the springs 33.

On the inner face of each end piece 21 is a ledge 35 having aperturestherethrough through which project pins 36 which carry at their upperends a plate 37 Mounted on said pins 36 between the ledges and theplates 37 are coiled springs 38 at each end of the machine, whosecombined strength is greater than that of the springs 33.

Extending upwardly and forwardly from the rear sides of the bearingmembers 3 and 4 to a point above the plates 37 are arms 39, which carrya rod 40 at their upper ends. Journaled on said rod 40 above the plates37 are the cam levers 4l-which have cams 42 at their lower ends whichbear on the plates 37. The upper ends of said levers are connected by anoperating bar 43 by means of which the levers may be simultaneouslyoperated. Each lever 41 is provided with a stop-block 44 on its outerside, which blocks are adapted to rest on the arms 39 when the leversare at their rearward limit of movement, to limit said movement in thatdirection. For the purpose of operating said rollers a drive shaft 45 isjournaled in bearin'gs 46 carried on a bracket 47 at one end of themachine. A worm .48 is rigidly secured on said shaft and meshes with aworm gear .49which is carried on a stud shaft 50 journaled on thebearing member 4. Rigidly secured on the shaft 50 is a pinion 51 whichmeshes with a gear 52 on the trunnion 9 of 1 front of the machine is thework table 56 the roller 7. The rollers 19 and 20 are provided at theirends with bearing trunnions 53 which are journaled in the bearings 27,and rigidly secured on the trunnions at the end of the rollers adjacentto the gear 52 are gears 54 which are adapted to mesh with the gear 52when the carriage is lowered. As shown, the shaft 45 is provided with apulley 55 adapted to be driven from any suitable source of power.

Supported on the members 3 and 4 at the which partially overlaps and ison a level with the top of the roller 7. The work is supported on saidtable while'being fed to the rollers. Extending forwardly at each end ofthe machine, and slightly below the table 56 is a work supporting rod57, which 1s preferably formed of wood. Upon one of sa1d rods thearticles to be operated upon may be hung, and upon the other thefinished work may be hung.

A tray 58, formed of sheet iron or other suitable material, is supportedbetween the frames 1 on the upper rods 2, and at the rear of the machinethe tray extends u wardly to a' point behind the rollers. T e upper edgeof the tray is turned rearwardly to provide a hook 59 which engages overthe rod 60 supported on the arms 39. This method of mounting the traymakes it re- .movable so that it may be kept clean.

The operation of the construction shown is as follows: The operatorlights the burner and when the heating roller has become sufficientlyheated power is applied to the pulley 55 to set the heating roller inmotion. The operator then pulls the bar 43 forwardly thereby causlng thecam levers 41 to compress the springs 38 and force the carriagedownwardly against the tension of the sprlngs 33 until the gears 54 arein mesh with the car 52. I p

The 010 hes tobe ironed are hung upon one of the rods 57 in convenientposition for the operator to get and feed into the machine. The articlesafter passing between the rollers drop into the tray 58 where theoperator may remove them from the front of the machine and hang them onthe other rod 57.

Obviously the ironing operation may be instantly stopped by throwing thelevers 41 rearwardly thereby releasing the tension of the springs 38 andpermitting the springs 33 to force the carriage upwardly and throw thegears out. of mesh. By adjusting the hand wheels34 on the shafts 32 thepressure of the compression rollers 19 and 20 may be regulated.

While I have shown and described but one embodiment of the invention, itWill be understood that many details of the construction shown may bevaried or omitted without departing from the scope of the claims.
